Not essential to the main thesis of the article, but still: "But let's just say you're okay with Apple sharing your fingerprints with the NSA, as I've already told you, they're not private at all."

Ok, they are not private but I'd still not willingly put them on anything controlled by an US corporation. Govt sending their agents to collect my fingerprints from glasses? Not feasible, too costly. Agency asking Apple to fetch the fingerprints willingly provided by the population "just in case"? Maybe not today and not tomorrow but in a few years? I wouldn't bet on them not doing it. And once there you're just one false positive away from some serious shit happening to you.
